TO ALL WI-IOM IT MAY CONGERN: i

Be it known4 that I, GEORGE A; ROBINSON, of Mount Pulaski, in the co'unty ofLogan, and Stute of Illinois, have invented a new and improved Washing Machine; and I do hereby declarethe following to be a full, clear, and exact description of the same, sucient to enable one skilled in the art to which the invention appertains to make use of it, reference being had to the accompanying drawings\vhich form a parto this specification, and in which- Figure 1 is a plan or top view.

Figure 2 is a vertical longitudinal section. V

`In this machine the concave clothes-bed is formed of rollers journalled in ,a frame which is supported, through the intervention of vertical rods passing through the end boards of the machine.' upon springs attached underneath the suds box. The revolving corrugated roller is driven by a wheel and pinion. which-,gives it an effective speed.

In the drawings, A is the suds box, having within it a suspended frame, B, carrying the concave bed of rollers C, uponl whichthe clotheslie as the corrugated roller D revolves above'them, and feeds them through from one end of the sudsrrbox to the other, and back again, until, by the consecutive pressure between the rollers D C, and the soaking at either end, the result is satisfactorily accomplished. The roller D is driven by a crankewheel, E, and pinion, F, the latter on theshaf't of the roller; and by'an arrangement oi' gearing the` speed of the roller is so increased as to render the machine very eiective: t' the end of the frame B are plates G, resting. upon the rods H, which pass vertically through the end boards of 'the suds box, and are supported upon the springs K, which are attached by plate and set-screws, L, to the bottom of the box. By these means a'moderate and graduated pressure is attained, as between the surfaces D C and the clothes passing' between them. A

I am aware that the concave bed of rollers has been supported upon .elastic bearings, which` enable it to yield to unusual pressure; but in all such cases the springs have been exposed to the suds inside the box, where they 'rust or rouland lose their elasticity and usefulness. In my machine the springs and their necessary connections are not exposed to wet,y andare far more' lastingand ,effective than those otherwise arranged. i

Having described my invention, what I claim therein as new,` and desire to secure by Letters Patent, is-

Thenrrangement of the geared roller D, and the concave bed C,yielding fra-me B, connections G H, and outside springs K, attached to the 'bottom of the box substantially as described and represented.
